Description

TECHNICAL AREA

[0001] The present disclosure relates to an electric bicycle theft detection system and an electric bicycle theft detection method, and in particular to an electric bicycle theft detection system and an electric bicycle theft detection method that are capable of detecting the theft of an electric bicycle and generating a warning signal to alert a user. BACKGROUND

[0002] Generally, bicycles are frequently used as a means of transport for short distances, for exercise or hobbies, for health purposes, and the like. In recent years, electric bicycles, which are equipped with a motor to provide power for longer distances or to reduce the user's physical exertion, have been widely introduced to the market.

[0003] The electric bicycle is configured to assist riding by means of a motor, detecting when the rider pedals. A battery and motor are attached to a bicycle that would otherwise only be propelled by muscle power. For this purpose, in addition to the motor and battery, the electric bicycle includes a reduction gear to reduce the rotational force of the motor, a power transmission device to transfer the rotational force output of the reduction gear to the wheels, and a control device to operate the reduction gear and the power transmission device.

[0004] Furthermore, the user of the electric bicycle can change and control the motor's rotational force via the control device. The electric bicycle also includes a speed detector, installed to detect the pedal rotation speed, or a torque detector installed in the motor to more precisely control the motor's drive by detecting the user's pedal force when riding on an incline, such as uphill or downhill.

[0005] Furthermore, the electric bicycle is divided into a pedal assist system (PAS) procedure and a throttle procedure according to a drive procedure.

[0006] Pedal Assist System (PAS) is a method of powering a motor by detecting when a user presses a pedal, using a sensor mounted on the pedal, etc. Most PAS systems are designed to adjust power levels from low to high power assistance. PAS systems include a speed-detection system, which detects pedal rotation and transmits power, and a torque-detection system, which detects pedal pressure, pedal rotation, and rotational speed. The speed-detection system is inexpensive but can create a noticeable difference in the riding experience, while the torque-detection system detects the user's pedal torque and thus produces a relatively subtle difference in the feel of the bicycle.

[0007] The throttle grip method is a method for riding a bicycle like a motorcycle without turning a pedal, by operating a button or lever / grip attached to a handlebar.

[0008] Furthermore, chainless electric bicycles are also appearing. These chainless electric bicycles move by converting energy from a user pedaling into electricity via a generator connected to the pedal. This electricity is stored in a battery and then used to power a motor. With this type of electric bicycle, it's possible to improve acceleration by controlling the motor to suit the riding environment, implementing an automatic shifting function by adjusting the gear ratio between pedal speed and drive wheel speed, and amplifying the power applied to the pedal by the user according to an intuitive ratio.

[0009] Electric bicycles are now relatively expensive, and users can suffer significant financial losses if they are stolen. Therefore, there is a need for technology that can detect the theft of an electric bicycle and help users react quickly.

[0032] In the following, embodiments of the present disclosure are described in detail with reference to the accompanying drawings, so that those skilled in the art in this field of technology can easily put the present disclosure into practice. However, the disclosure can be implemented in various different forms and is not limited to the embodiments described herein.

[0033] Furthermore, in several embodiments, components with the same configuration are described representatively using the same reference numerals in a first embodiment, and only components that differ from those of the first embodiment are described in a second embodiment.

[0034] Please note that the drawings are schematic and not to scale. Relative dimensions and proportions of parts in the drawings are exaggerated or reduced for clarity and convenience, and all dimensions are for illustrative purposes only and are therefore not limited. The same reference symbols are used to denote similar features for the same structures, elements, or parts that appear in two or more drawings.

[0035] One embodiment of the present disclosure represents, in particular, an ideal embodiment of the present disclosure. As a consequence, various modifications of the diagram are to be expected. Accordingly, the embodiment is not limited to a specific shape of the depicted area and includes, for example, a deformation of the shape during manufacturing.

[0036] In the following, an electric bicycle theft detection system 101 according to a first embodiment of the present disclosure is described with reference to the Fig. 1 to Fig. 1 and Fig. 2 described.

[0037] Fig. Figure 1 illustrates an electric bicycle 200 to which, by way of example, an electric bicycle theft detection system 101 according to a first embodiment of the present disclosure is applied. Fig. Figure 1 illustrates an electric bicycle 200 without a chain as an example, but a person skilled in the art can apply the present invention with suitable modifications and variations to other electric bicycles driven by chains.

[0038] As in Fig. As illustrated in Figure 1, the electric bicycle 200, to which the electric bicycle theft detection system 101 is applied, can comprise a front frame 10, a middle frame 20 and a rear frame 30.

[0039] The front frame 10 can include a front wheel 12 and a steering rod strut 14 to which the steering rod unit 13 is connected.

[0040] The steering rod unit 13 includes a handlebar stem 15 coupled to the lower end of the steering rod strut 14, a handlebar 16 coupled to the steering rod strut 14, and a handlebar grip 17 installed on the handlebar 16.

[0041] The handlebar stem 15 can be provided to adjust the height of the handlebar unit 13, and the handlebar rod 16 can be provided to make steering a bicycle manageable.

[0042] Furthermore, the handlebar grip 17 is equipped with a user interface device 210, which displays the status of the electric bicycle 200 to the user and transmits a user request to the control device 270 via a button or a display. The user interface device 210 can be electrically connected to the control device 270 either wired or wirelessly. The user interface device 210 can also generate a warning signal. This warning signal can include an audible alarm that announces the theft with a loud noise in the vicinity.

[0043] A generator 21 is provided at one end of the central frame 20, and pedals 220 can be rotatably mounted on either side of the generator 21. When the user rotates the pedal 220, that is, when the pedal 220 generates rotational energy, the rotational energy of the pedal 220 can be converted into electrical energy in the generator 21, and the electrical energy of the generator 21 can be stored in the battery 23 provided in the frame 20.

[0044] Additionally, the central frame 20 can also have a seat post 25 for installing a saddle 24. The seat post 25 is height-adjustable and coupled to the seat tube 26, which projects from the rear of the central frame 20.

[0045] A rear wheel 240 is rotatably mounted on an end section of the rear frame 30. A motor 250 for propelling the electric bicycle 200 forward by rotating the rear wheel 240 is mounted in the center of the rear wheel 240. That is, the rear wheel 240 becomes the drive wheel. However, the rear wheel 240 is not necessarily the drive wheel, and so if the motor is attached to the front wheel 12, the front wheel 12 can be the drive wheel. As such, any wheel that rotates by receiving power, be it the front wheel 12 or the rear wheel 240, can be the drive wheel. In the following description, the rear wheel 240 will be referred to as a drive wheel.

[0046] Apart from that, the positions of the battery 23 and the control device 270 are not limited to those shown and can be installed in the rear frame 30 instead of the middle frame 20.

[0047] The pedal speed detector 230 can measure the rotational speed of the pedal. For example, the pedal speed detector 230 can be installed on a rotating shaft of the pedal 220.

[0048] The drive wheel speed detector 260 can measure the rotational speed of the drive wheel 240. For example, the drive wheel speed detector 260 can be installed on a rotating shaft of the drive wheel 240.

[0049] The electric bicycle theft detection system 101 according to the first embodiment of the present disclosure comprises a pedal 220, a pedal speed detector 230, a drive wheel 240, a motor 250, a drive wheel speed detector 260, a control device 270, and a user interface device 210 among various components of the electric bicycle 200 described above.

[0050] Additionally, in the first embodiment of the present disclosure, the torque of the motor 250 can be measured by a torque detector attached to the motor 250, or it can be calculated indirectly by measuring a current applied to the motor 250.

[0051] The control device 270 can detect a theft based on the speed of the pedal 220, the torque of the motor 250 and the speed of the drive wheel 240.

[0052] In particular, if the rotation of the drive wheel 240 is measured while the pedal speed 220 and the motor torque 250 are 0, the control device 270 can detect a theft and, if a preset reference time has elapsed in a state where theft is detected, the control device 270 can control the user interface device 210 to generate a warning signal. For example, the warning signal can be an audible alarm that announces the theft with a loud noise in the environment, or it can be a visibly flashing red light, like a warning light. Additionally, a signal can be generated in various forms so that a user can recognize the fact of a theft. Here, a reference time can be set differently according to the environment in which the electric bicycle 200 is used and can be selected by a user as needed.

[0053] With such a configuration, the electric bicycle theft detection system 101 according to the first embodiment of the present disclosure can detect a theft of the electric bicycle 200 and immediately notify the user of the fact that a theft has occurred.

[0054] In this way, by notifying the user of the theft detection information that the electric bicycle 200 is considered stolen, an immediate response is possible if the user is nearby, and helps to report the theft promptly, even if the user cannot directly check the theft detection information.

[0055] In addition, the user is alerted to a dangerous situation and can optionally sound a warning tone in the electric bicycle 200.

[0056] The following describes an electric bicycle theft detection method using the electric bicycle theft detection system 101 according to the first embodiment of the present disclosure with reference to the Fig. 3 and Fig. 4 described in detail.

[0057] First, the rotational speed of the pedal 220, the rotational speed of the drive wheel 240, and the torque of the motor 250 can be measured. Here, the torque of the motor 250 can be measured using a torque detector or calculated using an applied current.

[0058] Next, a theft is detected based on the rotational speed of the pedal 220, the rotational speed of the drive wheel 240, and the torque of the motor 250. The determination of whether the theft is detected is carried out by the control device 270. In the theft detection step, the rotational speed of the drive wheel 240 is measured while the rotational speed of the pedal 220 and the torque of the motor 250 are 0, thus enabling the theft to be detected.

[0059] Next, if a theft is detected, a warning signal is generated to alert the user. Specifically, during the user warning step, a warning signal can be generated if a preset reference time elapses while the theft is detected. The warning signal can be executed by the user interface device 210 under the control of the control device 270. The user interface device 210 can generate a warning tone, announcing the theft with a loud sound or a warning signal in various forms to inform the user that a theft has occurred.

[0060] The reason for setting a delay before warning a user after a theft has been detected is that the drive wheel 240 of the e-bike 200 can also rotate temporarily in a non-theft situation, making it possible to filter out and remove any false alarms after this period. This, in turn, prevents the user from being warned too frequently about theft in harmless situations.

[0061] As described above, according to the electric bicycle theft detection procedure, it is possible to detect the theft of the electric bicycle 200 and to immediately notify the user of the fact that a theft has occurred.

[0062] In the following, an electric bicycle theft detection system 102 according to a second embodiment of the present disclosure is described with reference to Fig. 5 described.

[0063] As in Fig. As shown in Figure 5, the electric bicycle theft detection system 102 according to the second embodiment of the present disclosure can further comprise a gyroscope sensor 280 for detecting the operating state and / or a global positioning system (GPS) for tracking a location. Additionally, the control device 270 can detect a theft by taking into account information provided by the gyroscope sensor 280 or the global positioning system.

[0064] More precisely, the control device 270 can detect a theft if the gyroscope sensor 280 detects an actuation or the global positioning system (GPS) detects a position movement, while the rotational speed of the pedal 220, the rotational speed of the drive wheel 240 and the torque of the motor 250 are 0.

[0065] Additionally, the control device 270 can control the user interface device 210 to generate a warning signal when a preset reference time elapses in a state where theft is detected. Here, the reference time can be set differently according to the environment in which the electric bicycle 200 is used and can be selected by a user as needed.

[0066] With such a configuration, the electric bicycle theft detection system 102 according to the second embodiment of the present disclosure can also detect the theft of the electric bicycle 200 and immediately notify the user of the fact that a theft has occurred. The electric bicycle theft detection method using the electric bicycle theft detection system 102 according to the second embodiment of the present disclosure is described below with reference to the Fig. 6 and Fig. 7 described in detail.

[0067] First, the rotational speed of the pedal 220, the rotational speed of the drive wheel 240, and the torque of the motor 250 can be measured. Here, the torque of the motor 250 can be measured using a torque detector or calculated using an applied current.

[0068] In addition, activation is detected by the gyroscope sensor 280 or a location is tracked by the global positioning system (GPS).

[0069] Next, a theft is detected based on the rotational speed of the pedal 220, the rotational speed of the drive wheel 240, the torque of the motor 250, and the information provided by the gyroscope 280 or the global positioning system (GPS). The determination of whether the theft is detected is carried out by the control device 270. In particular, during the theft detection step, if the gyroscope 280 detects actuation or the global positioning system (GPS) detects positional movement, while the rotational speed of the pedal 220, the torque of the motor 250, and the rotational speed of the drive wheel 240 are all zero, the theft can be detected.

[0070] Next, if a theft is detected, a warning signal is generated to alert the user. Specifically, in the user warning step, a warning signal can be generated if a preset reference time elapses while theft is detected. The warning signal can be executed by the user interface device 210 under the control of the control device 270. The user interface device 210 can generate a warning tone, announcing the theft with a loud sound or a warning signal in various forms to alert the user that the theft has occurred.

[0071] Accordingly, it is possible to detect the theft of the electric bicycle 200 and to immediately notify the user of the fact that the theft has taken place.

[0072] As described above, the electric bicycle theft detection method according to the first embodiment and the electric bicycle theft detection method according to the second embodiment can be applied selectively according to the type and power of the electric bicycle 200 and can be selected by the user according to the environment in which the electric bicycle 200 is used.

[0073] In the following, an electric bicycle theft detection system 103 according to a third embodiment of the present disclosure is described with reference to Fig. 8 described.

[0076] Furthermore, the electric bicycle 200 may also include at least one gyro sensor 280 for detecting an operating state and / or a global positioning system (GPS) for tracking a location.

[0077] If the electric bicycle 200 further includes the gyro sensor 280 or the global positioning system (GPS), the control device 270 can detect a theft by reflecting the information provided by the gyro sensor 280 or the global positioning system (GPS).

[0078] Furthermore, the electric bicycle 200 can also include a user interface device 210 that generates a warning signal when the control device 270 detects a theft.

[0079] The mobile device 500 manages the electric bicycle 200 and can be equipped with an application to display theft detection information when a theft is detected and to generate an alert. This means that even if a user is far away from the electric bicycle 200, the theft detection information of the electric bicycle 200 can be checked using the mobile device 500.

[0080] The cloud service 400 can receive information transmitted by the modem terminal 290 of the electric bicycle 200, update stored information and transmit the updated information to the mobile device 500.

[0081] In particular, the cloud service 400 can include a web application server 420 that communicates with the modem terminal 290 of the electric bicycle 200, a database server 430 that integrates and stores information collected by the web application server 420, and an application programming interface (API) gateway 450 that transmits information stored in the database server 430 to the mobile device 500.

[0082] In the third embodiment of the present disclosure, the control device 270 of the electric bicycle 200 can detect theft when the rotation of the drive wheel 240 is measured, while the rotational speed of the pedal 220 and the torque of the motor 250 are 0.

[0083] If the electric bicycle 200 includes the gyro sensor 280 or the global positioning system (GPS), the control device 270 can also detect a theft if the gyro sensor 280 detects the actuation or if the global positioning system (GPS) detects the position movement, while the rotational speed of the pedal 220, the rotational speed of the drive wheel 240 and the torque of the motor 250 are 0.

[0084] Furthermore, if a preset reference time elapses in a state where the theft has been detected, the control device 270 can transmit the theft detection information to the cloud service 400 via the modem terminal 290.

[0085] The Cloud Service 400 can transmit the received theft detection information to the mobile device 500 to notify or warn the user about the information.

[0086] Furthermore, in the third embodiment of the present disclosure, the user interface device 210 of the electric bicycle 200 can display the theft detection information provided by the control device 270 or generate the warning signal.

[0087] With such a configuration, the electric bicycle theft detection system 103 according to the third embodiment of the present disclosure can detect the theft of the electric bicycle 200 and immediately notify the user of the fact that a theft has taken place.

[0088] In particular, according to the third embodiment of the present disclosure, the user can even check the theft detection information via the mobile terminal 500 in a state far removed from the electric bicycle 200.
